Add a new EHCI driver for Broadcom STB SoC's. A new EHCI driver
was created instead of adding support to the existing ehci platform
driver because of the code required to workaround bugs in the EHCI
controller. The primary workround is for a bug where the Core
violates the SOF interval between the first two SOFs transmitted after
resume. This only happens if the resume occurs near the end of a
microframe. The fix is to intercept the echi-hcd request to complete
RESUME and align it to the start of the next microframe.

Adding a new EHCI platform-specific driver is okay with me.  However,
this patch does not include most of the changes you discussed with
Greg.  I assume you will submit a revised version with those changes in
place; when you do I will Ack it.

I mistakenly sent a partially fixed version instead of the version
with all the fixes (git stashed). I'm sending v8 will all the fixes.

Thanks
